My C3 has the same itchy skin problems too mostly due to the 1001 allergies he hasā¦but I use the Aveeno Oatmeal Ointment to help calm the itch & I also put Brewers Yeast tablets & Fish Oil tablets into his food to help keep his skin & coat healthy.
Sometimes we need to bathe regularly (like once a week :eek:) in the Aveeno oatmeal shampoo to help as well.
Good luck!
